We look at the division of 84243626 by 619 
The aim is to understand the frequency of 619 in 84243626.

Advancing to step 1:
8 divided by 619 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 619

Advancing to step 2:
If we divide 84 by 619, we get 0 and a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 619

Moving on to step 3:
619 can be fit into 842 1 times, resulting in a remainder of 223.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 619 from 842 to get 223.
Take the next digit (4) from the dividend and append it to 223, then repeat: 2234 / 619

Moving on to step 4:
If we divide 2234 by 619, we get 3 and a remainder of 377.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1857 from 2234, we get 377.
Include the next digit (3) from the dividend after 377, then repeat: 3773 / 619

On to step 5:
619 can be fit into 3773 6 times, resulting in a remainder of 59.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we subtract 3714 from 3773, we get 59.
Grab the next digit (6) from the dividend, add it to 59, then carry on: 596 / 619

Let's proceed to step 6:
When dividing 596 by 619, we get 0 with a remainder of 596.
The next digit of our result is 0. 
Result so far: 1360.0
Subtracting 0 from 596 leaves us with 596.
Include the next digit (2) from the dividend after 596, then repeat: 5962 / 619

Advancing to step 7:
If we divide 5962 by 619, we get 9 and a remainder of 391.
Write down 9 as next digit of the result. 
Result so far: 13609.0
Subtract 5571 from 5962 to get 391.
Grab the next digit (6) from the dividend, add it to 391, then carry on: 3916 / 619

Let's proceed to step 8:
3916 divided by 619 is 6 with a remainder of 202.
Put 6 as the next digit of the answer. 
Result so far: 136096.0
Subtract 3714 from 3916 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 9:
If we divide 2020 by 619, we get 3 and a remainder of 163.
Use 3 as the next digit of our solution. 
Result so far: 136096.3
Subtract 1857 from 2020 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 10:
619 can be fit into 1630 2 times, resulting in a remainder of 392.
The number 2 becomes the next digit in our result. 
Result so far: 136096.32
The remainder is 392 after subtracting 1238 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 11:
619 goes into 3920 6 times with a remainder of 206.
The number 6 becomes the next digit in our result. 
Result so far: 136096.326
Deduct 3714 from 3920 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 12:
619 can be fit into 2060 3 times, resulting in a remainder of 203.
The next digit of our result is 3. 
Result so far: 136096.3263
If we subtract 1857 from 2060, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 13:
When dividing 2030 by 619, we get 3 with a remainder of 173.
The number 3 becomes the next digit in our result. 
Result so far: 136096.32633
The remainder is 173 after subtracting 1857 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

The final result is 136096.32633 with a remainder of 0.000173.
